Security enhancement of speech scrambling using triple Chaotic Maps

This paper proposed a new approach to improve the security of Chaos based on using triple of different Chaotic Maps, include Chen, Lorenz and Henon Maps for speech scrambling. These Chaotic Maps using to generate secret key. Also, the paper use linear and non-linear functions to calculate the secret key, thatit uses in speech scrambling process. The main goal of the use of triple Chaotic Maps is to increase the key space. Therefore, the proposed system hasa good level security.
